Are there any reasons for kids to wear pajamas, as opposed to clothes, for sleeping?
Yes. While it might seem reasonable to put a child to bed in comfy, loose-fitting clothes, there are two good reasons not to: Hygiene and fire. Kids come in contact with a lot of bacteria during the day, and an evening bath can rinse some of those microbes away, decreasing the risk of infection, Dr. Lisa M. Asta, a San Francisco pediatrician and spokeswoman for the American Academy of Pediatrics, said in an e-mail. Perhaps even more important: Put a child to bed in snug-fitting and/or flame retardant pajamas to minimize the risk of serious burns in case of fire.
